Study Notes
Cefazolin Overview
- Cefazolin, marketed as Ancef®, is an intravenous (IV) antibiotic.
- Frequently utilized for surgical prophylaxis to prevent infections during and after procedures.
Pharmacological Characteristics
- More resistant to beta-lactamase enzymes compared to penicillins (PCNs), enhancing effectiveness in certain infections.
- Administered IV as oral forms would be destroyed by gastric acid, ensuring drug stability and efficacy.
Pharmacokinetics
- Renally eliminated, requiring dose adjustments in patients with renal impairment to avoid toxicity.
- Inactivated by beta-lactamase, though it demonstrates greater stability than traditional penicillins.
Clinical Considerations
- Potential for cross-sensitivity with other beta-lactam antibiotics, necessitating careful patient history review for allergies.
